Commercial sealant contractors in Furzedown, done properly

Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the paperwork side is in order: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on external facade joints, window and door perimeters and movement joints in walls and floors, and the usual reasons a site gets in touch are movement joints packed with grit and debris and gaps behind commercial kitchen worktops and sinks. For commercial sealant work in Furzedown, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

On a typical commercial building in Furzedown, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Around Furzedown, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered

Does a hotel in Furzedown need to shut while its sealant is renewed?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Can you work at a site such as Mitcham Industrial Estate, by Furzedown?

Yes. Estates, retail parks and business parks around Furzedown, Mitcham Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Do you check for asbestos before removing sealant?

We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder, and we don’t remove asbestos-containing materials.

What site paperwork can you provide?

Let us know your requirements when you ask for a price, and the paperwork is confirmed with the quote. From you, we will need the asbestos information for older buildings and any site rules.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Does commercial sealant work come with a guarantee?

Our workmanship is guaranteed for 12 months. We are fully insured for public liability as well.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites around Furzedown. One quote can cover more than one site, which keeps the paperwork simple.

Maintenance after handover

To get the most from the new sealant:

  • Look at the sealant around anything that has been moved or replaced
  • Note dates and locations of sealant work for future planning
  • Make sure ventilation in wet areas is switched on and working
  • On pre-2000 buildings, share the asbestos information before work starts

Keep an eye out for other trades after we’ve gone. Shop refits, new services and replaced fittings often break the seal around them. If that happens, call 01277 525 020 or email a schedule or drawings and we’ll price putting it right.

Sealant installed at the same time normally fails in sequence. A few splits this year normally mean more next year so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.

What sets the cost

Quotes vary with the job. It mainly depends on:

  • Access and working height
  • Joint width, depth and condition
  • Quantities, in metres or numbers
  • Which sealant the job calls for

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.

What we need to price the job

However big the job, the same details help:

  • Your programme or deadline
  • Asbestos survey details if the building is older
  • Clear photographs of the problem areas
  • Drawings or a marked-up plan, if available

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a few hours to several days on most single sites, depending on joint lengths and access, and our waste is bagged and taken away as we go. All of Greater London is in the ULEZ, and kerbside space in Furzedown can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints

Getting a fixed quote

Shops, offices and hotels in and around Furzedown

In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We plan around them and agree phasing so tenants and customers aren’t disrupted. Furzedown has at least three named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal.

For a hotel such as Leigham Court Hotel (1.3 miles north-east of Furzedown), the colour of a joint at the bar or the bath matters to the look of the room. For premises near Tooting station, 0.6 miles south-west of Furzedown, footfall is part of the plan: work is phased so shops and offices keep trading. For a shop at a centre such as Priory Retail Park (1.5 miles south-west of Furzedown), tidy joints at counters and displays matter as much as the fixtures.

Furzedown is about 3 miles east of Wimbledon, in Greater London. We send applicators to Furzedown for sealant joints, handled exactly as we handle every other area. Across Greater London, 764 places are covered, including Furzedown. There’s a separate page for London, about 6 miles away.

Business premises anywhere in SW16, SW17 and CR4 are within our area. Among the streets we cover are Deal Road, Links Road and Seely Road, and sites on any of them can send details for a fixed quote.

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price, and we will confirm the colours available for the specified product.

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. We will recommend the right filler or sealant for the traffic and movement.
